    ^That text tells you it's unsupported but technically works (at least for some degree, definitely up to the point of activation). I think it was the same for any previous WDMM 2.7 preview drivers.

    Yeah, NvidiaFreak650 said he had it unchecking itself though, but I guess since everyone else is saying it works from a clean install it must have just been a spook in his system.

    That's what I always do when installing drivers with DDU and it works with any other driver but as soon as internet comes back on, Windows overrides this particular 450 driver.
    I saw that option, I suppose I'll try it then. Any idea what it changes on the system exactly? Could be ExcludeWUDriversInQualityUpdate registry value?
    upd: apparently it changes SearchOrderConfig to 0.

    People still hope for magical tricks to boost performance...

    So has anybody witnessed a mighty boost with this feature?

    No, they don't. The last time I checked their WDDM 2.7 preview drivers still had HAGS disabled and didn't have any control panel (at least in the leaked packages). Nv has it all (all the new features with full installer package including NVCP and the rest) in the form of developer preview or Fast Ring WU downloads.
    AMD has stable WDDM 2.6 drivers like nV and a few WDDM 2.7 beta drivers which are not public (or fully leaked), not on WU and are useless for the likes of us anyway (offer nothing new for the user to play around with).

    Here's the official summary of WDDM 2.7. And still no mention of HAGS either.
    https://docs.microsoft.com/en-us/wi...w-for-windows-10-display-and-graphics-drivers
    And I still don't find anything else public regarding HAGS except from the vague "Reduce latency and improve performance" description that Windows itself has.

    The AMD driver itself is undeniably WDDM 2.7, what individual features it supports is still up in the air.

    So I was technically correct. The best kind of correct

    technically correct is also technically incorrect though.

    Ahh. My bad, 20.5 is indeed WDDM 2.7 already even though HAGS is still blacklisted (at least for Vega).

    Hmm. My screenshots above show HAGS returned to default Off position when I ran an in-place upgrade with the official ISO (just in case because the early upgrade with the UUP->ISO source was wonky on my notebook, so I refreshed all 20H1 installs from the MS ISO yesterday). The drivers didn't change during the refresh upgrades (both were already at place and WU didn't override them).

    Did a clean DDU install of 450.99 just now and yeah it seems to work fine. At least GPUsched is available and doesn't reset after reboots, GPU-Z also reports it as enabled. DCH version.
    Although one weird thing I noticed is I had DDU remove DCH control panel but after driver install I had panel available even with internet disabled. Might be that NVCP is packed with DCH in this case just like Standard.

    You live on technicalities? Sounds risky.

    Damn, and I thought it was working (if I assume he means "not officially supported" as "not currently functional")! Thank you for forwarding this.
